If what you sold was a group of assets that included goodwill, then both you and the buyer need to file Form 8594, a form which is not supported by any version of TurboTax.
See https://www.irs.gov/pub/irs-pdf/f8594.pdf
Regardless, with respect to the sales price and personal goodwill, the allocation of the sales price to goodwill is generally reported as the sale of a capital asset (i.e., capital gain). Therefore, you would report that sale in the Investment Income section (Stocks, Mutual Funds, Bonds, Other).
